Dispersion Entropy: A Measure for Time-Series Analysis

IEEE Signal Processing Letters, 2016
One of the most powerful tools to assess the dynamical characteristics of time series is entropy. Sample entropy (SE), though powerful, is not fast enough, especially for long signals. Permutation entropy (PE), as a broadly used irregularity indicator, considers only the order of the amplitude values and hence some information regarding the amplitudes ...

Dispersion measures and entropy for seizure detection

2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
Electroencephalogram (EEG) is an important technique for detecting epileptic seizures. In this paper a method of classification of EEG signal into normal, interictal and ictal classes is presented. Statistical measures such as median absolute deviation (MAD), variance and entropy showing the dispersion and rhythmicity, were calculated for each frame of

Dispersion Entropy for the automated detection of epileptic seizures

2020 IEEE 15th International Conference on Industrial and Information Systems (ICIIS), 2020
The electroencephalogram (EEG) is a powerful tool for evaluation of seizure activities in the human brain. This paper introduces Dispersion Entropy (DispEn) as a feature extraction method for the first time in the automated detection of epileptic seizures.

Dispersion—An Entropy Generator of Diffusion

Journal of Energy Resources Technology, 1998
In multicomponent gaseous flows with chemical reactions, diffusion is usually considered to be a single-source entropy generator. Introducing the concept of dispersion, where the atom balance is dominant rather than the molecular, shows in an ideal setting that, even when there is diffusion, the dispersion part of entropy generation can be reduced to ...

Topological entropy of semi-dispersing billiards

Ergodic Theory and Dynamical Systems, 1998
In this paper we continue to explore the applications of the connections between singular Riemannian geometry and billiard systems that were first used in [ 6 ] to prove estimates on the number of collisions in non-degenerate semi-dispersing billiards.
